Eiffel POSIX binding

e-POSIX gives Eiffel programmers access to the familiar Unix API. Either as raw calls, but also in the form of classes with full Design By Contract support. e-POSIX file and socket classes can be used as a plugin where Gobo's KI_INPUT_STREAM and KI_OUTPUT_STREAM are expected. So you can now directly parse input coming from a TCP socket.

The goal of e-POSIX is to provide a 100% complete Eiffel binding to Standard C, POSIX and the Single Unix Specification.

e-POSIX can also be used on Windows systems through its portability layer. This allows you to create native Windows programs that use file descriptors, sockets, pipes and can read and write the input and output of child programs. The Cygwin UNIX emulator is also supported, but not needed. When using Cygwin, e-POSIX just thinks that it is running on Unix.

e-POSIX got a 2nd place at the Eiffel struggle 2000!

Released at 2008 January 2 is version 3.0.1, the current official release. This is a minor update for the 3.0 released at 2007 May 18, and Windows users are urged to upgrade. It is targeted at ISE 5.6 (and 5.7), VisualEiffel 5.0 and SmartEiffel 1.2r7. The most important user visible list of changes between 2.4 and 3.0 is:

EPX_HTTP_CLIENT: supports HTTPS now (needs the openssl binary).
STDC_FILE: now supports writing of strings with %U characters.
More Gobo compatible: use name instead of path or filename and end_of_input instead of eof.
SUS_TEMPORARY_FILE: creates temporary file for which a filename is available.
POSIX_CONSTANT: all POSIX error codes added.
EPX_HTTP_10_CLIENT: read_response_with_redirect: new method to read a response and follow up on redirects until the redirects end.
EPX_XML_WRITER: strict checks for name and content validation.
EPX_CGI: support for PUT method.
Better support for multithreading in ISE Eiffel.
Important bug fixes, including format string vulneratibility in SUS_SYSLOG.

Download

You can download the tar.gz release or zip release. For VisualEiffel users who do not have Microsoft Visual C, there is a precompiled eposix library. You don't have to compile the C sources in this case. Rename this file to libeposix_ve_msc.lib and put this file in the lib subdirectory of eposix.
